I have an MN12 from my '04 GTO removed and sitting undercover at MTI. It was removed at about 4,800 miles to make way for a Viper trans as part of the new build-up. The trans was in perfect functioning condition and was not in any way broken or trashed. The GTO made two visits to HRP and less than 10 launches on slicks, the last of which was in May. I'll take $1000 for it. No need to ship, just bring your f-bod over to MTI. PM me if you're interested.

Externally it's the same as an Fcar T56 (M6), except it has a "rearward-reaching" shifter. Internally it has different synchronizers(whats called a tripple-cone package) and, more significantly, a different gearset.The ratios are the same as the ZO6 Corvette application( 2.97 1st gear)
